In this study, measured the distribution of heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Zn) in the surface water of Vellar estuary, Southeast Coast of India. The concentration of heavy metals was measured by atomic absorption spectroscopy(AAS) instrument. Heavy metals concentrations were found to decrease in sequence of Fe >Cu>Pb>Zn> Cd >Cr> Ni. Results showed that heavy metal concentrations in the marine surface water generally exceed the criteria of international marine water quality. Moreover, both the contamination factor (CF) and pollution load index (PLI) values suggested the elevation of heavy metals concentration in the region. The results revealed that the heavy metal concentration was higher during Post -monsoon season in water of the year 2020 and the order of concentration Fe>Zn>Cu>Cd>Pb>Cr>Ni. As a result, the purpose of this research was to find out what other heavy metals (Pb, Cd, Cr, and Zn) were in the water.

Marine ecosystem is being threatened by the discharge of untreated sewage wastes and industrial effluents which u ltimately affects the sustainability of living resources and public health. These wastes carry enormous level of to xicants especially the heavy metals have the tendency to accumulate into the basic food chain and move up through the higher trophic level and results in negative impact on the marine resources thus causing economic loss. In this regard, to ascertain the level of heavy metals in water, part iculate, zooplankton (Zn, Mn, Pb, Cu, Cd and Hg) and in sediment (Pb, Al, Cd and Hg) along southern Kerala coast, India has been evaluated during early 2006. The heavy metal concentrations followed the hierarchy; Zn>Mn>Pb>Cu >Cd >Hg; Pb>Zn>Mn>Cu >Cd >Hg; Zn>Pb>Mn>Cu >Cd >Hg and Pb>A l>Cd>Hg in seawater, particulate matter, zooplankton and sediment respectively. The results revealed that in all the transacts (except Cochin) the heavy metal concentrations are below the threshold levels associated with the toxicolog ical effects and the regulatory limits. Metal enrich ments were observed close to the major urban areas of coastal waters, mostly associated with large scale industrialization. Enrich ment factor, geoaccumulat ion index and pollution load index were calcu lated to evaluate the heavy metal threats along the coastal sediment. It revealed minor to moderately severe enrich ment of Cd, Pb and Hg in the industrial zones of the coastal stretches especially at Cochin. A co mparison with sediment quality guideline quotient indicated that there may be probability of ecoto xicological threats to the benthic community along Cochin transect.
The concentration of heavy metal levels (Cu, Zn, Cd, Pb, Fe, Cr, Mn, Ni and Co) were measured in sea water samples by using Niskin sampler at different depths (10, 20, 30, 40 and 50 mts) and different areas (Visakhapatnam, Rushi konda and Bheemili) with the help of fisherman boats of east coast of Andhra Pradesh, India. Metals are analysed by using ICP-MS (Inductively coupled plasma mass spectrometry) and statistical analysis were done by using one way ANOVA. Concentrations of Cu range in between 8.03±0.09 and 21.21±0.01 ppm at 40 mts depth of Rushi konda coast and Bheemili coast, Zn levels was observed in the range of 22.05±0.83 and 37.05±0.56 ppm, Cd was found in between 0.51±0.16 and 5.36±0.04 ppm, lead was accumulated from 4.63±1.78 to 17.19±0.15 ppm, Fe accumulated from 28.31±1.47 to 40.86±1.05 ppm, Cr was found in between 6.47±0.28 and 16.82±1.16 ppm, Mn was observed in between 3.29±1.01 and 14.67±2.37 ppm, Ni ranges from 6.18±0.54 to 14.38±1.08 ppm and finally Co was accumulated in between 2.71±0.19 and 8.32±2.31 ppm respectively. The mean values of all the metal accumulation in Visakhapatnam coast is Zn>Fe>Cu>Pb>Ni>Cr>Mn>Co>Cd, Rushi konda coast is Fe>Zn>Cr>Cu>Ni>Mn>Co>Pb>Cd and Bheemili coast is Fe>Zn>Cu>Cr>Mn>Ni>Pb>Co>Cd. Based on the order of accumulation the metal content was more and it results pollution was more in the coastal sea water due to release of industrial wastes and anthropogenic activities.

The study of heavy metal distribution in coastal water and surface sediments is an important component in understanding the distribution levels as well as assessing the cause of anthropogenic influences on the marine ecosystem. During the last Twenty Five years, the coastal environment of southeast India had experienced intense developments in industry, urbanization and aquaculture. Several metals are known to be discharged frequently through industrial and domestic effluents along the southeast coast of India. The present study was carried out to determine the Heavy Metal Distribution in the coastal Waters and sediments of Mandapam, Thoothukudi, Arumuganeri and Kanyakumari Coasts. The sampling of coastal water and sediments was carried out from October 2013 to September 2014. The enrichment in the concentration of heavy metals in the samples that are close to the coastal areas indicated that higher concentration was due to the anthropogenic activities in the coastal area. Hence, this present study used to investigate the Heavy metal levels of contamination in this area, and also useful for further impact evaluation.

Heavy metal toxicity studies were conducted using water samples collected in 2019 and 2020 from Parangipettai, Pazhaiyar, Poompuhar, Karaikal, and Velankanni. All of these samples were collected in the summer, either after or right before the monsoon hit. The samples were taken at a location a kilometre or two inlands from the shore, where two streams converged. Cadmium, chromium, copper, iron, nickel, lead, and zinc are the PPM heavy metal parameters. The sea confluence point has the highest concentration of iron pollution and heavy metals. The laboratory has implemented quality control and assurance procedures to guarantee the reliability of the results. Methods such as standard operating procedure adherence, standard calibration, blank analysis, etc. Analyzing duplicates and piecing together newly added components. Each experiment was repeated three times, with the average result used for analysis. To eliminate bias, we used the same statistical procedures on all samples. Each chemical element was analysed using the same methods as those used by the analytical laboratory.
The objective of the present study was to characterize the concentrations of selected dissolved trace metals in the coastal waters (500 m from shore) of Kalpakkam, Tamil Nadu, India. The order of dissolved concentration of these metals was found to be as follows: Co (cobalt) , Cd (cadmium) , Cr (chromium) , Mn (manganese) , Cu (copper) , Ni (nickel) , Pb (lead) , Zn (zinc). The levels of these trace metals were found to be relatively low as compared to the reported values for other Indian coastal waters, which indicates negligible pollution at this location. Cadmium was the only metal found to increase its concentration during the monsoon period, suggesting its allochthonous input. Factor analysis indicated that chromium, nickel, zinc, cobalt, copper, manganese, and lead were of common origin, and external inputs through land runoff had nominal or little impact, typifying in-situ regeneration and remineralization linkage with their temporal variation. However, levels of zinc, cobalt, and copper remained relatively high during the summer period, and abrupt increases in their concentration during December (monsoon season) may be due to their dual (autochthonous as well as allochthonous) input.

Heavy metals are non-biodegradable which cause cytotoxic and carcinogenic effects in animals. Being at the top of the aquatic food chain fish constitute a major source of heavy metals in food. The seasonal variation in Cu, Cr, Zn, Pb and Cd concentrations found in muscle tissue of five marine fishes species (Mugil cephalus, Terapon jarbua, Sardinella longiceps, Liza partian and Chanos chanos) of the polluted Ariyankuppam estuary, Puduchery coastal waters in relation to that of estuary water sampled during throughout the year 2010, evaluated using an atomic absorption spectrophotometer. Heavy metal concentrations in Ariyankuppam estuarine water decreased in the order of Zn > Cd > Cu > Pb > Cr on the all seasons. In this present study, the highest concentration of Zn found on the post monsoon followed by Cr, Pb observes on premonsoon season and Cu, Cd noticed on monsoon season. The lowest concentration of Zn, Cr found on monsoon followed by Pb, Cd found on post monsoon and Cu noticed on premonsoon seasons. In the fishes, the heavy metal is highly accumulated in Cu C. chanos (6.55 ±0.244 µg g-1) at premonsoon, Cr (1.60 ±0.14 µg g-1) in T. jarbua at monsoon, Zn (16.24±0.25 µg g-1) in S. longiceps at monsoon, Pb (4.14 ±0.13 µg g-1) in L. partia at premonsoon, Cd (6.74 ±0.57 µg g-1) in T. jarbua at premonsoon seasons in this estuary. Almost all the heavy metals (Cu, Cr, Zn and Pb) concentrations in the estuary water and muscle tissue of marine organisms within the permissible limits and Cd were exceeded permissible limits.

The coastal stretch of Kendrapada district of Odisha is also known as Gahirmatha; located at eastern region of Odisha, these regions are known for estuary of the rivers Dhamra, Baitarani and Brahmani. Gahirmatha Beach located in Bhitarkanika providing a large base for millions of Olive Ridley Turtles, which is known to be one of most important nesting beaches for turtles in the world. In recent years, heavy metals pollution of the aquatic environment has become a worldwide problem due to materialistic behaviours, intrinsic tenacity, toxicity and non-biodegradable in nature. The study area is situated between the latitude 20 0 25' 00''N to 20 0 32' 00''N & longitude 86 0 45' 00''E to 86 0 48' 00''E.This study aimed to determine the concentrations of the heavy metals (Mercury as Hg, Vanadium as V, Chromium as Cr, Manganese as Mn, Iron as Fe, Cobalt as Co, Nickel as Ni, Copper as Cu, Zinc as Zn, Arsenic as As, Lead as Pb, Molybdenum as Mo, Cadmium as Cd) and also there distribution in the water collected from the eastern part of Bay of Bengal from four different estuary locations of Gahiramatha coast, Odisha .The concentrations of heavy metals was measured using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The heavy metals concentrations were found in decreasing sequence of Zn> Fe> Cu> Cr> V> Co> Mn>Ni> Pb> As>Mo> Hg> Cd. The variation of relative concentrations of some of the heavy metals may be affected basically by two reasons; the first one is the riverine influence through both Dhamra and Brahmani river. The second reason behind it may be the anthropogenic liberation through local activities; that are may responsible for the change of water quality.
